That's the nice thing about collectd, it has several write plugins for 
different use cases.

At $WORK we replaced rrd with graphite on the server side (i.e. clients' 
collectd send the data to a central collectd server with write_graphite 
plugin).

It took some configuring but now it's working marvelously.
There is some in-memory caching but since graphite's web API reads from 
disk+memory, your graphs won't lag behind usually.

Cheers!
